I discovered the dress - a new arrival to H&M - and it immediately went into my shopping basket. It may seem plain, but there is something exceedingly sexy about a long-sleeved mini dress. And it will keep your arms warm, too. The material has a velour finish which gives it an edge and adds to the warmness. I had a dress just like it that I got in Dunnes about ten years ago and I honestly wore it to death. It was just one of those pieces that worked really hard. This one will be the same. You can wear with bare legs or tights and you can style it in different ways by changing your hair and jewellery and accessories.

For the Christmas party look, you have to wear it with these red sandals from Penneys. They're only €11, they're in a festive colour - and, anyway, everyone needs a pair of red shoes. Again, make it work for the tone of your Christmas party by changing up the extras (things you already own, of course). Add long, dangly earrings for a fancier 'do, and none at all for if it's that more casual. Pop on some 'fashion tights' for your work party - and a Santa hat if needs be.
